Insert the brass tubes through three of the

holes. They should be arranged so as the long

one will be on the right side of the plane and

the short one on the left side.

The tubes should extend out the front of the

cap 5/8”. Bend the long tube up at about a 20

degree angle. This should be adjusted so the

end of the tube almost touches the top of the

tank when installed.

Install the 4mm silicone tube to the short

brass tube and install the clunk to the other

end of the silicone tube. This is the fuel pick-

up and must be free to “flop” around in the

tank so it can pick up fuel in any attitude.

Install the assembly into the tank so the vent

tube is turned up to the top of the tank and is

positioned on the right side of the tank.

Tighten the screw to expand the rubber cap.

Don’t over tighten or you could split the tank.

5. Attach the three pieces of 5mm tubing to the

three tank outlets. They are different colors so

you can tell which are the two vents and which

is the fuel pickup after the tank is installed.

Make a note of which color you attach to

which tube. The short brass with the clunk is

the fuel pickup and must go to the carburetor.

One of the long brass tubes is the vent and

should go to the pressure outlet on the muffler.

The second vent can be used for filling the

fuel tank but will have to be plugged with a

screw (Not Included) so that the fuel will not

run out.

INSTALLING THE FUEL TANK

Collect the following items:

(1) Fuel Tank
(1) Fuel Line
(4) #2 x 5/16 phillips Head Screw
(1) Wood Hatch Cover

Install the fuel tank into the fuselage.

Place some foam around the fuel tank (foam

not included).

Note:

If you are using a engine that needs to pressur-

ize the fuel system then wrap the fuel tank in

string reinforcing tape to prevent splitting when

under pressure.

The tank provided is for glow fuel only.
